Still can not call my Subclass method returns. J2EE

I guess the correct question is: How do I put the #2 above my while loop and only ask for it when ready?.... I thought I was already doing that.

Post#45 suggested there be two loops:
1) to get the data
2) to display the data

I have implemented 2 while loops and using my if conditionals inside the loops.... I still am having the problems with showing my contacts.... I get both when I am supposed to show business, I get duplicate when I am supposed to show personal, and both works fine.

What did you change?
The question is still OUTSIDE of the loop?
There are more questions inside of the loop.

I thought there were to be two loops:
// First loop to process input and save it
begin loop1
question about input
process input
end loop1

// Second loop to display input from above
begin loop2
question about display
do requested display
end loop2

Did I mention that my initial display has to give options
1) add business contacts
2) add personal contacts
3) show contacts --then lead to which contact
4) exit

So it should look like:

1) ask initial questioning (see above)
2) create loop through 1-2 till complete
3) upon choosing 3 (ask user which contact) ,loop through till desire selection is complete
4) display the correct contact
5) terminate program

How can the initial display show option 3 if there are not any contacts entered yet?

Is the design shown in post#49 wrong?
Can there be an intermixing of adding contacts and showing contacts?
Or are they separated as shown? Do all of one BEFORE doing the next.

I still must be able to give the option to show the unpopulated file and produce it if so desired...... Stupid I know, but none the less it is what is required... It would have been a lot easier the other way around.....

Ask for contact input, when done ask which for which contact wanted to be shown.

IN the beginning of the main method, I create both txt files that are going to be written on..... That way I can call an empty file if needed.

Then back to one loop with the questions inside and at the top of the loop.

That is what I have saying .... I still get issues with run-time.

You haven't changed the code as I suggested.

As I run a single While loop at the beginning, I get a continues loop when I select which contact to view.....

Is this the basic layout?


***Ask initial question
While loop (1-4)
1)If add Business{some action}
2)else if add Personal{some action}
3)else if view contact{(Ask which contact to view)
While loop(1-3)
****1a)if view Business txt file
**** 2a)else if view Personal txt file
**** 3a)else view both txt files
else{quit}

While NOT 1-4{inform user not valid, and rerun from beginning}

Why are there 2 while loops?
How does the code exit the 2nd loop if the control variable's value isn't changed?

At the end of the code, I change the user's input to the exit #4

Example: "enter" is the variable I am using for 1-4 (with 4 being the exit) ....At the end of the code for 1a-3a, I put "enter = 4"; this exits and terminates the program.

Code:

---

  if(showCont == 1 )
              {
              try {
                        File file = new File("business.txt");
                        FileReader fileReader = new FileReader(file);
                        BufferedReader bufferedReader = new BufferedReader(fileReader);
                        StringBuilder stringBuffer = new StringBuilder();
                        String line;
                        while ((line = bufferedReader.readLine()) != null) {
                                stringBuffer.append(line);
                                stringBuffer.append("\n");
                        }
                        fileReader.close();
                        System.out.println("Contents of file:");
                        System.out.println(stringBuffer.toString());
                } catch (IOException e) {
                    System.out.println("You have an error that is not priting!!!!");}
             
                //showCont = newShow;
              enter = 4;
             
              }

---

Why have a while loop if it will only execute once? Why not use an if statement?

I have removed all WHILE loops except at the beginning, now I have an infinite loop when I select to view my contact.
